Description
The Bleak is a slender, silvery freshwater fish native to Europe and Western Asia, known for its active, schooling behavior. It typically inhabits clear, flowing waters and feeds on small invertebrates and zooplankton. While sometimes kept in large aquariums or ponds, it requires cool, well-oxygenated water to thrive.
